Description

An Impactite is rock created or modified by one or more impacts of a meteorite. Impactites are considered metamorphic rock, because their source materials were modified by the heat and pressure of the impact. On Earth, impactites are made primarily of modified terrestrial material, sometimes with pieces of the original meteorite.
A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario. An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet.
Formed by the Impact of the huge object that created the Chicxulub structure, this material was originally obtained from the Deer River, Alberta and has come from an old collection.

The Cretaceous–Tertiary (K-T) boundary, is a geological signature, usually a thin band of rock and marks the end of the Cretaceous Period, the last period of the Mesozoic Era, and marks the beginning of the Paleogene period. Its age is usually estimated at around 66 million years. The K–T boundary is associated with the mass extinction event, a mass extinction which destroyed a majority of the world’s Mesozoic species, including all dinosaurs except for birds.

Strong evidence exists that the extinction coincided with a large meteorite impact at the Chicxulub crater and the generally accepted scientific theory is that this impact triggered the extinction event.

ACTUAL AS SEENThe image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
